We're dividing 15219 by 53 
Let's see how many times 53 fits into 15219.

Step 1:
1 divided by 53 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 53

Advancing to step 2:
53 can be fit into 15 0 times, resulting in a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Include the next digit (2) from the dividend after 15, then repeat: 152 / 53

Going ahead to step 3:
152 divided by 53 is 2 with a remainder of 46.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 106 away from 152, we end up with 46.
Take the next digit (1) from the dividend and append it to 46, then repeat: 461 / 53

Step 4:
The number 53 fits into 461 8 times, leaving a remainder of 37.
Put 8 as the next digit of the answer. 
Result so far: 28.0
Subtract 424 from 461 to get 37.
Fetch the next digit (9) from the dividend, attach it to 37 and continue: 379 / 53

Step 5:
53 can be fit into 379 7 times, resulting in a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 287.0
If we subtract 371 from 379, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 6:
53 goes into 80 1 times with a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 287.1
If we take 53 away from 80, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 7:
53 goes into 270 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 287.15
Subtract 265 from 270 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
If we divide 50 by 53, we get 0 and a remainder of 50.
The next digit of our result is 0. 
Result so far: 287.15
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 9:
If we divide 500 by 53, we get 9 and a remainder of 23.
Write down 9 as next digit of the result. 
Result so far: 287.1509
Subtract 477 from 500 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 10:
The number 53 fits into 230 4 times, leaving a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 287.15094
Subtract 212 from 230 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 11:
The number 53 fits into 180 3 times, leaving a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 287.150943
Subtract 159 from 180 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 12:
The number 53 fits into 210 3 times, leaving a remainder of 51.
Write down 3 as next digit of the result. 
Result so far: 287.1509433
Subtracting 159 from 210 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

After the division, we end up with 287.1509433 and a remainder of 5.1e-07.
